The CR (Control Room Output) Option Card provides an additional set of 1/4” TRS balanced outputs suit-
able for playing back via a stereo monitor system. These outputs are controlled by the front panel
VOL/MUTE output level control. This option will be available Q4 of 2016.
11 USB Setup
11.1 Computer Audio Requirements
The m108 ships with a standard USB type A to type B cable. The type A connector plugs in to the com-
puter and the type B connector to the m108 USB jack.
The m108’s asynchronous mode USB controller supports standard driverless operation on Mac OSX
since version 10.8.5. Sample rates up to 192kHz are supported. For Windows 7, 8, 8.1, and 10 PC comput-
ers, users will need to download and install them108 USB driver on their computer. This driver can be
found on our website:
http://www.gracedesign.com/support/support.htm
On Mac computers driverless operation basically means the m108 will automatically show up in your
computer’s list of supported audio devices as ‘m108’. The m108 will provide 8 input channels and 2 out-
put channels. In most cases, simply choose the m108 as your audio recording or playback device and the
system will work.

11.2 Using the m108 as a DAW Interface
With the extremely high quality audio recording and playback, the m108 can be a great option as a
stand-alone I/O device with your digital audio workstation. However, using it in conjunction with other
USB audio devices connected to your workstation computer’s USB buss will require some adjustments to
your computers audio settings.
For Mac OS X, this is achieved by setting up the m108 in an ‘aggregate audio device’ setup, with the
m108 as the default input and playback` device.
With both of these setups, if you are using multiple I/O devices, you will need to pay careful attention to
clocking. In Mac / Core audio aggregate setups, you are able to set which device is the clock master.
However, this means that other devices may be sample rate converted, which we do not recommend.
